*Value at the end of period*-

*Value at the beginning of period*)/

*Value at the beginning of period*] x 100

**For example:**

Percent Change in X = [ (

*12- 8*)/

*8*] x 100

Therefore,

Percentage Change in X = [4/8] x 100

= 0.5 x 100

=

**50 %**

Therefore the answer is 50%. You can even further calculate percent change over time.

Calculate Percent Change Over Time

You can calculate year to year change to understand the rate of inflation or deflation from one period to the next. This is very useful to understand the worth of your investment in money. You need to use the following formula:

Percent Change = {(

Here, N stands for the number of years between the two values of past and present.

Percent Change = {(

*Value Present*/-*Value Past*)/*Value Past*x 100}/ NHere, N stands for the number of years between the two values of past and present.

**For example**, if there was a difference of 5 years between the values of past and present then, percent Change in X = [ (

*12- 8*)/

*8*] x 100

Therefore,

Percentage Change in X = [4/8] x 100

= 0.5 x 100

= 50/ 5

Thus, percentage change over time =

**10%**

Calculate Percent Change Between Two Numbers

You can calculate percent change between two numbers on the basis that you are either considering a reduction in value or increase in value. The reduction in value will result a higher percentage change and increase in value will give a decreased percentage change. This is due to the higher base that results in a lower percentage for any given change in value. Just follow the given example to understand how to calculate percent change between two numbers.

Percent Change = [(Value Present - Value Past)/Value Past] x 100

Percent Change = [(Value Present - Value Past)/Value Past] x 100

**For example,**

Percent Change- [($25,000 - $ 20,000) /$ 20, 000] x 100

= $5,000 / $ 20,000 x100

= 0.25 x100

=

**25%**

Therefore the percent change between two numbers is 25%.

In Excel

If you are working on an excel sheet and need to calculate percent change, you will not find any built-in function. In order to calculate percent change in excel you will need to use the following formula:

Percent Change = (

You can even use an alternative formula to calculate percent change in excel:

Percent Value = (

Percent Change = (

*new_value*-*original_value*)/ABS(*original_value*)You can even use an alternative formula to calculate percent change in excel:

Percent Value = (

*new_value*/*original_value*)-1
